This invention relates to improvements in aeroplanes and has articular reference to a wing construction t erefor.

An object of the invention is to provide an improved construction wherein the disposition of the sections of a 'wingrelative to each other is such as to secure a maximum lifting power from any given area of wing surface.

Another object is to divide a wing into spaced sections all having some portion thereof arranged in the same horizontal plane with other portions of one section disposed at an angle to each other and to the plane of another section.

The above and other objects will appear more clearly from the following detailed description, when taken in connection with the accompanying drawings, which illustrate preferred embodiments of the inventive. idea.

In the drawings Figure 1 is a fragmentary plan view of an aeroplane showing one form of the invention;

Figure 2 is a front elevation thereof;

Figure 3 is a fragmentary side elevation;

Figure 4 is a front elevation of another form;

Figure 5 is a fragmentary side elevation of the form shown in Figure 4;

Figure 6 is a fragmentary plan view of another form; c Figure 7 is a fragmentary side elevation of the form shown in Figure 6;

Figure 8 is a fragmentary plan view of 35 still another form,

Figure 9 is a front elevation thereof; v ligure 10 is a fragmentary side elevation; an

Fi ure 11 is a fragmentary plan view of a 40 still urther form.

All of the figures of the drawin s illustrate more or less conventionally the selage 12 and landing gea'r13 of an aeroplane.

In the embodiment of the invention shown l in Figures 1 to 3, the fuselage 12 supports a wing consisting of front and rear sections 14 and 15, respectively,- each having its rear edges provided at both ends with ailerons, conventionally shown at 16. The entire area of the front section 14 is in the same horihaving its central portion in the same plane zontal plane extending transversely of the fuselage 12 on opposite sides thereof. The rear section 15 has its central portion 17 arranged in the same horizontal plane with the section 14' but the end portions of said sectiom 15 on opposite sides of the portion 17 are inclined upwardly so that each end portion will be disposed diagonally relative to the section 14 and in a plane above the same. Figures 4 and 5 illustrate the same general principle of arranged portions-of one-section of the wing in planes above the other section with at least one other portion of the first named'section in the same horizontal plane with said other section. Thus, the wing in this instance is divided into horizontally spaced front and rear sections 18 19, the former being of the same formationas the section 14. The section 19, instead 'of with the section 18, as in Figure 2, has said portion disposed in a plane above the latter section and the ends of the section on opposite sides of said portion are inclined downwardly until the outer extremities thereof are 7 disposed in the same plane with the ends of the section 18.

In Figures 6 and 7 there is shown a further adaptation of the inventive idea, in which the wing is divided into three horizontally spaced sections 20, 21 and 22. The central section 21 is of the same construction as the sections 14. and 18, while the front and rear sections 20 and 22 are, respectively, of a format-ion like the sections 15 and 19 so that throughout the combined spread of said sections 20 and 22 there will'be at least one portion disposed in a horizontal plane above the section 21 and at least one portion in the same plane therewith. In each instance the sections 20, 21 and 22 are provided with ailerons 23 arranged similarly to the ailerons 16.

A further embodiment of the invention is shown in Figures 8 to 10 wherein the wing is divided into three horizontal spaced sections 24, 25 and 26 all arranged in the same plane and provided at the extremities of their rear edges with ailerons 27.

The form of the invention shown in Figure 11 comprises a wing having two horizontally spaced sections 28 and 29 of the same construction and disposed in the same horizontal plane. Each section, in this instance, is provided at each end with front and rear ailerons 30 and 31 arranged along the longitudinal edges of the section. Additionally, the extremities of said sections are provided with the end ailerons 32.

What is claimed is:

1. An aeroplane comprising a wing divided into sections arranged one behind another and in close proximity to each other, one of which sections has a central portion disposed in a plane above and parallel to that of the other section, and end portions which extend diagonally downward from said central portion, the extremities of said end portions being in the same horizontal plane with said other section.

2. An aeroplane comprising a wing divided into front, center and rear sections spaced horizontally, said center section having its entire area in the same horizontal plane, one of the remaining sections having a central portion disposed in the same plane with the center section and its ends inclined upwardly from said central portion, and the other of said remaining sections having a central portion arranged in a plane above that of the center section and having its extremities dis posed in the same plane with the latter section. I

3. An aeroplane comprising a wing divided into sections arranged one behind another, one of which sections has its entire area arranged in the same horizontal plane, and another of said sections having a portion in the plane with the first named section and the remainder thereof extending diagonally relative tosaid first named section and only on one side thereof.

4. An aeroplane comprising a wing divided into sections arranged one behind another, one of which sections has its entire area in the same horizontal plane, and the other section having one portion in the plane of the first named section and other portions which extend diagonally from said first named section and upwardly relative to the latter section.

In testimony whereof I have aflixed my signature.

ANTHONY ,LANZETTA.
